Excerpt from A Moveable Feast - Forward to F. Scott Fitzgerald Ernest Hemingway

His talent was as natural as the pattern that was made by the dust on a butterfly's wings. At one time he understood it no more than the butterfly did and he did not know when it was brushed or marred. Later he became conscious of his damaged wings and of their construction and he learned to think. He was flying again and I was lucky to meet him just after a good time in his writing if not a good one in his life.
